Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Database Mirroring in High Performance mode
Why it's wrong here
This is a deprecated feature and does not provide the same benefits as Availability Groups.
- ✓
Synchronous-commit Availability Group
Why this is correct
Synchronous commit ensures the secondary is fully up to date, providing zero data loss failover.
- ✗
Log Shipping
Why it's wrong here
Log shipping is not an automatic failover solution and is subject to latency.

Asynchronous-commit Availability Group
Why it's wrong here
Asynchronous commit does not guarantee zero data loss as the secondary might be slightly behind.
